LIGHTING-FIXTURE.

Application filed-April 21, 1914. Serial No. 833,377.

enable others skilled in the art to Which it appertainslto make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a vertical section through my improved lighting fixture. Fig. 2 is a bottom view of the canopy, the globe having been removed.

My invention relates to lighting fixtures, and specifically to a form of electrical lighting fixture which is'designed with the object of providing a strong, cheap, and easily assembled fixture which will beeffective and ornamental.

The device is designed particularly for use as a semi-indirect lighting fixture, although it is obvious that it maybe used also for indirect difl'usion of the light.

As illustrated in Fig. 1, l represents the ceiling construction in which is secured the outlet box 2. The outlet box 2 is provided with a screw threaded stud if upon which is a sleeve 5. A threaded nipple 6 is supported in the sleeve 5, and the relationship of the stud 4, sleeve 5, and nipple 6 is such as to permit adjustment of the latter to the proper position relative to-the ceiling, and to accommodate outlet boxes of different depths.

The lighting fixture is made up of a re-' taining strap 7 which is adapted to be secured against the ceiling by a clamping nut 8 which screws on to the outer end of the nipple 6, the said strap 7 being provided with an aperture to permit the pails- T e ends of the strap 7 are turned over as shown at 7 to provide supporting flanges, and to these flanges is secured the canopy 9, the screws 9 or .other suitable securing means being employed.

The fixture wires 10 pass from the outlet box at either side of the strap 7, to the socket 11 which is supported in a suitable apron 12 properly fastened on the inside of the canopy 9, and shaped to conform to the interior contour of the neck 9* of the canopy.

On the exterior of the canopy are suitably secured the spring holders 14, of which there are preferably three, arranged equi-distant about the circumference of the canopy. These spring holders are hooked at their lower ends, and are adapted-to engage under the rim of the globe 15. This globe'may be of translucent material for semi-indirect lighting, or may be of enameled steel or .other reflective material for indirect lighting. The lamp 16 is screwed into the socket 11 in the. usual fashion, the. mountings thereof being concealed by the skirt portion 9 of the canopy.

It will be understood that the socket 11 1S made in two parts, whichseparate on the line of the apron 12, one part being inserted above the apron and. the other part below the apron, whereupon the two are clamped or screwed together. As the means for securing. the spring holders 14.- and apron 12 upon the canopy, I preferably employ screws M? which engage both the holders and the apron 12 and are secured in position by the lock nut 14"., The canopy is preferablyyfinished in brilliant white enamel so as to provide a highly reflective surface particularly adapted to reflect and diffuse the light reflected upwardly from the lamp. As can be seen, the exterior contour of the canopy is of general ogee outline, which cgpformation provides a reflector adapted to diffuse the light eflectively over a considerable area. I

It will be seen that this fixture is very economical to manufacture, andthat it can be assembled with great facility and rapidity.

t The fixture is assembled by first clam ing the strap 7 against the ceiling by t e clamping nut 8, making the proper wire connection with the plug 11, fitting the plug into the apron 12, placing the canopy in position on the retaining flanges 7 and securing it thereto, 7 placing the lamp in the socket, and placing the globe in the holders. This construction also "provides a very cleanly fixture, as the globe may be readily removed to clean it and'the various other parts by simply springing the holders 14 outwardly by pressin the globe upwardly, then slightly tilting-t e globe so that it will disengage from the hooks, and removing it downward. In replacing the globe, it is simply placed against the lower ends ofthe spring holders and forced upwardly, wheretion, and a suitable globe adapted to be supported by said holders. p

2. A light-111g fixture comprising a canopy adapted for attachment to a ceiling, a lamp supported on and depending below the canopy, a globe having an outwardly turned and downwardly directed rim portion,

resilient holders secured to the outer portion of said canopy and having depending hooked. extremities adapted to engage beneath the downwardly directed rim of the globe to support it from the canopy; said holders having. spring tendency to hold them in engagement with the globe In testimony whereof I hereunto ufiix my signature in the presence of two Witnesses, this 6th day of April, 1914.
